"Did you end up leaving any extra wiggle room for expansion this time around, or did you find another workaround?"
Honestly, I'm not totally convinced that leaving extra wiggle room is always the best approach. Sure, it can help with expansion and contraction, but sometimes it just invites more issues down the line—like debris buildup or water pooling. I've seen roofs where the extra space ended up being a magnet for leaves and dirt, eventually causing drainage headaches.
Have you considered maybe using flexible edging materials instead? Something like rubberized metal edging or even recycled composite materials can adapt better to temperature fluctuations without needing that extra gap. Plus, they're often more eco-friendly and durable in the long run. I know it's not the traditional route, but sometimes stepping away from standard practices can save you headaches later on...
Good points about debris buildup—I've definitely seen that happen. But wouldn't flexible edging still need a bit of space to move around? I mean, even rubberized stuff expands a little, right? I've never tried composite materials myself...do they really hold up well over time? Curious if anyone here's had them installed for more than a couple seasons and how they're holding up.
"I mean, even rubberized stuff expands a little, right?"
Yeah, good point—pretty much everything moves a bit, especially with temp swings. I haven't personally installed composite edging, but I've seen it after a few storms and it seemed to hold up pretty well. Still, I wonder how it fares long-term with UV exposure...does it fade or get brittle eventually? I'd hate to swap metal for something that looks great at first but turns sketchy after a few summers.
I've been wondering about composite edging too, but honestly, metal might still be the safer bet. My neighbor installed composite trim a couple years back, and while it hasn't cracked or anything yet, it's definitely faded quite a bit. UV exposure seems to dull it down faster than you'd think. Metal might expand and contract slightly, but at least you know it'll hold its shape and color longer term...just something to consider before making the switch.
Metal edging definitely has its advantages, especially when it comes to durability and UV resistance. If you're leaning toward metal, just make sure you account for thermal expansion. Leave a small gap (about 1/8 inch) between sections to allow for movement, and use fasteners with neoprene washers—they help absorb some of that expansion stress. Composite can look great initially, but yeah, fading is pretty common. Metal's usually the safer long-term bet if you're after consistency.
